Trying to migrate 2012 materials to Revit 2013 I found a bug about the behavior of material categories.

In the materials list all previous material classes show as categories and that's fine. But anytime you make a change to a material and if its class is not one of the listed types under descriptive information, it gets listed as generic next time you open the material browser.

Easiest way to replicate the problem is to actually import a material from one of the Autodesk Libraries.

Open your Material Browser and import "Bamboo" material listed under "Flooring" from the Autodesk's AEC Library.

You'll see it lists fine under your Document Materials with the correct category "Flooring". Next, OK to close the Material Browser and then reopen it by clicking Materials. You'll see Bamboo's category changed to "Generic".

To sum it up, if your material's category is not one of the hardcoded types under Descriptive Information it always reverts to "Generic".

If you have hundreds of materials nicely classified by your logical naming from previously releases, you could find yourself having to reassign them with one of the limited types provided by Revit 2013. 

Please confirm by going through the above process to make certain it's a bug that could be adressed in the upcoming update.

Thanks,

This bug is making a mess of our material library. Any update on this issue? Will a fix be issued?

I am having same problem with document materials not accepting library category assignments when replacing materials for company material library.  It doesn't make sense and creating a problem.  Can someone please assist?

I would also like to know of any updates.

Any people from Autodesk that will enlighten us on this issue amongst the other unintuitive workflows of this messy material broser and assets editor.
